LED + SSL

Below is my lighting column published in the January issue of tED Magazine. Reprinted with permission. The majority of LED lamps and luminaires feature an electronic driver that performs the same basic function as a fluorescent ballast. The driver converts AC supply voltage to DC and drives current to the LED source. In the traditional [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy DOE’s LED Lighting Facts® program has come out with a handy new tool for lighting designers and specifiers, which can make their job a whole lot easier. The LED Lighting Facts Specification [...]

My contributions to the December issue of ELECTRICAL CONTRACTOR included a prominent feature on flicker in light sources, notably LED. What’s being done about it at the industry level and what specifiers can do about it to ensure good performance. The article begins: Flicker in light sources is an old problem made new again in [...]

The U.S. Department of Energy recently posted the presentations from the 2016 DOE SSL Technology Development Workshop, held November 16–17 in Denver. Tunable-white lighting, connected lighting, TLEDs, OLEDs, controls and more. Check it out here.

The U.S. Department of Energy’s CALiPER program has released a new Snapshot report on LED downlights. Among the key findings of the new Snapshot, which is based on DOE’s LED Lighting Facts database: • Across all products listed with LED Lighting Facts, average efficacy gains continue to track at about 10 lm/W per year. • [...]

ARCHITECTURAL LIGHTING recently published an article evaluating OLED general lighting technology and the obstacles facing broader adoption. Check it out here.

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy Among the many possibilities enabled by the advent of SSL is the use of light to trigger or suppress certain physiological responses of living things — from humans, to animals, to plants. [...]

A recent contribution to tED Magazine. Reprinted with permission. The Department of Energy (DOE) recently updated its bi-annual report, Energy Savings Forecast of Solid-State Lighting in General Illumination Applications. This major report models adoption of LEDs in the U.S. general lighting market. In 2015, LED products comprised an estimated 6 percent of the total installed [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy Not too long ago, solid-state lighting was more of an intriguing possibility than a practical solution. The majority of SSL products on the market back then were all over the map in [...]
